(ii) is towed (or is to be towed) only by a prime mover that is registered in the name of the registered operator of the trailer and is one of a number of semi-trailers for carrying goods registered in that person's name; and
(b) the number of semi-trailers for carrying goods registered (or to be registered) in the registered operator's name exceeds the number of prime movers registered in the registered operator's name; and
(c) the trailer did not travel more than 20 000 kilometres in the last preceding period of 12 months or, if being registered for the first time, is unlikely to travel more than 20 000 kilometres in the 12-month period immediately after it is registered.
(2) A registered operator of a trailer is entitled to a rebate of 40% of the motor tax that would, but for this subregulation, be payable in respect of the trailer if the Registrar is satisfied, by statutory declaration or otherwise that –
(a) the trailer is an interchangeable trailer; and
(b) the registered operator has a number of semi-trailers registered in his or her name; and
(c) the registered operator has paid the full amount of motor tax payable in respect of a number of semi-trailers equal to the number of prime movers registered in the registered operator's name.
(3) For the purpose of identifying a vehicle as one in respect of which a rebate applies under this regulation, the Registrar may issue a distinctive number plate for the vehicle.
(4) If the Registrar issues a distinctive number plate under subregulation (3) , the person to whom the number plate is issued must –
(a) affix the number plate to the vehicle in accordance with these regulations; and
(b) keep it so affixed for the registration period (or the part of the registration period for which the rebate applies).
Penalty: Fine not exceeding 10 penalty units.
(5) If, during a period for which a rebate is granted under this regulation, the criteria for classifying the trailer as an interchangeable trailer are no longer satisfied, the entitlement to the rebate ceases.
(6) If the entitlement to the rebate ceases, the registered operator of the trailer must, within 14 days –
(a) give the Registrar written notice of the cessation of the entitlement; and
(b) return any distinctive number plate issued for the vehicle (unless the Registrar authorises its retention); and
(c) pay to the Registrar a proportion of the rebate calculated in accordance with subregulation (7) .
Penalty: Fine not exceeding 10 penalty units.
(7) The amount to be paid to the Registrar is to be calculated in accordance with the following formula:
where –
A is the amount to be paid;
B is the number of days remaining of the period for which the rebate was granted at the time the entitlement ceased;
C is the number of days in the period for which the motor tax was paid;
D is the monetary amount of the rebate granted for the period for which the motor tax was paid.
(8) The registered operator of a trailer that is an interchangeable trailer must not, without the Registrar's written permission, cause or permit the trailer to be drawn by a prime mover that is not registered in that person's name.
Penalty: Fine not exceeding 20 penalty units.
(9) If the Registrar determines that the entitlement to the rebate has ceased, and gives written notice of that determination to the registered operator of the trailer, the registered operator must, within 14 days –
(a) return any distinctive number plate issued for the vehicle (unless the Registrar authorises its retention); and
(b) pay to the Registrar a proportion of the rebate equivalent to the proportion that the remaining part of the registration period (expressed in days) bears to the whole of the registration period (expressed in days).
